LEPIDOPTERA OF NEW YORK ANp NEIGHBORING STATES 147 



6. Fore wing dull ochre 8. concolor. 



6. Fore wing reddish yellow, margined with purplish fuscous. 



7. fuscomarginella. 

 6. Fore wing pale straw yellow, w r ith dark-dusted spots. 



13. albostraminea. 



1. T. malifoliella Clemens. Mouse gray, a little shining, the scale -tips showing 

 some golden iridescence. 6 mm. 



Larva on apple, starting in a linear mine, which is gradually widened into a 

 large blotch; but is not tentiform until the formation of the cocoon, when a fold 

 is made, to contain the pupa. Larva in August; moth in May. 



This moth, the " trumpet-miner ", is generally distributed. 



New York: Menands (Albany Co.), Schenectady, East Greenbush. The larval 

 work is seen throughout the State, but I have seen no records. 



2. T. aenea Frey and Boll. Similar to T. malifoliella, rather larger, distinctly 

 brighter and more purplish, with strong bronzy iridescence and purple apex; the 

 hind wing rather more nearly concolorous. 7 mm. 



The larva occurs on Rubus. The mine is generally straight, and runs to the 

 edge of the leaf, usually between two veins. The mine is crumpled in parallel folds, 

 much like that of the oak -feeding species and Lithocolletis. 



Massachusetts; Ohio; Pennsylvania; Texas. 



3. T. roseticola Frey and Boll. Indistinguishable from malifoliella in the adult 

 stage, but usually a little smaller, duller, with broader wings, slightly more roughly 

 scaled toward the apex, and with a yellower face. 



The larva is a trumpet miner on rose. 



4. T. ambrosiaeella Chambers. Head powdery dull brown; fore wing luteous, 

 heavily dusted with blackish, showing traces of the transverse bands of T. heliop- 

 sisella, the dark markings leaving two or three lightly dusted and more distinctly 

 yellow areas toward the outer margin. Fringe mouse gray with some black-tipped 

 scales. Hind wing mouse gray. 6 mm. 



The larva mines Ambrosia trifida and does not form a nidus. 



Kentucky; Ohio; Missouri. 



f>. T. heliopsisella Chambers. Deep ochre yellow. Fore wing with two oblique 

 gray fasciae from a third way out on costa to middle of inner margin and from 

 beyond middle of costa to three-fourths way out on inner margin; a costal streak 

 from the latter to the apex, and a streak in base of fold; all the black dusting 

 a white ground. 8 mm. (nolckenii Frey and Boll). 



The larva occurs on Heliopsis and Ambrosia, in August. It spins a circular 

 white nidus for shelter within the mine, and pupates in it. 



Southern Ohio; Kentucky; California. 



6. T. solidaginifoliella Clemens. Cream color or light straw yellow; shaded 

 with bright yellow, becoming yellow -brown in the costal fringe. Head solid yellow; 

 fore wing w'ith scattered spots of black dusting. 7 mm. 



August. Larva in a flat, white blotch on upper side of leaves of Solidago. 

 Pennsylvania to Texas. New York: Albany. 



7. T. fuscomarginella Chambers. The larva is a miner on the under side of oak 

 leaves. 



Kentucky. 



8. T. concolor Zeller. This species is known only from Texas. The mine is at 

 the edge of a leaf of oak. 



9. T. castaneaeella Chambers. Pale yellow, all the margins of the fore wing 

 strongly shaded and dusted with yellow brown ; the under side of the abdomen 

 contrastingly dusted with dark brown except at the apex. 8 mm. 



The larva forms a narrow blotch mine along the edge of a leaf of chestnut. I 

 have never seen a male. 

 Virginia; Kentucky.
